2 Claims.

This invention relates to direct connected implements and more particularly to an implement adapted for direct connection with a tractor for cultivating the soil and which implement is so structed as to provide for a relatively high degree of clearance between its supporting frame and the soil when i coupled to the tract imposed upon a n operation and which is so or as to reduce the tendency tractor by the direct coupling of a tool thereto to rear up.

Other objects and advantages of this inven tion it is believed will be apparent from the following detailed description of a preferred embodiment thereof as panying drawings.

In the drawings:

The

angles 3 are connected together at pbints spaced along their length by means transversely of the angles 3 in angles 4 secured of tool supporting pairs at the points where it is desired to secure the ground-working the frame I are ben posed attachment arms tools 5.

means for pivotally carried within the track There are thus provided connecting the forward end of the attachment arms to the tractor.

Means are provided for lifting the frame I relatively to the ground which means preferably includes a rock shaft II which is pivotally supported in spaced bearings l2 carried by a transversely extending bar by means of end plates l3 supported in position M which are secured at one end to the bar [3 and at their opposite ends are secured to the rock shaft and the power take Braces -l 5 connect frame of the tractor. The

Welded to the rock diagrammatically illustrated at l8 which is pro- 5 vided in connection with several forms of tractors. The structure of the lift mechanism I8 is well understood in the art so that it need not be specifically described here.

Secured to the shaft l l are lifting arms l9 which 10 extend under the frame I to engage a roller 20 carried by a bolt 2| and lifting brackets 22. The lifting arms H! at their point of contact with the rollers 20 are bent so that the engaging sur face thereof is substantially horizontal, permitting a relatively moving contact between the rollers 20 and the horizontal portion of the lift ing arms I9 as the frame I is elevated to the actuation of the lift mechanism l8.

In order to brace the frame structure, clips 23 are provided along the angles 3. The shanks 24 of the ground-working tools 5 are secured to the frame I by means of bolts 25 which are passed through holes formed in the ends of the shanks 24 and through the downwardly depending 25 flanges of the angles 4.

Having fully described my invention, it is to be understood that I do not wish to be limited to the details herein set forth, but my invention is of the full scope of the appended claims.

I claim:

1. In a direct connected cultivating implement for connection with a tractor having a power take-off, a frame including side arms which extend forwardly and downwardly to provide attachment arms, angles mounted between the arms in pairs to connect said arms, groundworking tool-supporting angles mounted in pairs and connected between the first said angles of the ground-working tools, means for securing the 40 ground-working tools between pairs of the latter said angles, and a lift structure supported between the frame and the tractor, and means connecting the lift structure with the frame and with a power lift of the tractor.

2. In a cultivating device adapted to be directly connected with a tractor having a power takeoff, the combination of a frame, a cultivating tool supported by the frame, attachment arms extending forwardly from the frame, means for 50 to rock the rock shaft as the power take-off is operated, lifting arms secured in spaced relation to the rock shaft and operatively engaging the said frame to lift the frame vertically relative to the tractor as the rock shaft is rocked, and rollers interposed between the said frame and the latter said lifting arms.
